L322 Logic 7 most fiber optic issues

Hi all . i have a 2005 4.4 V8 Autobiography Vogue L322.Has any body found a way of getting rid of the Logic 7 -most ring fiber optic ball ache as i have no sound from speakers and head unit turns it self off intermittently . I would like to fit android head unit but nobody does amp bypass for fiber optic. So im wondering is there a head unit that i could try to wire to speakers direct.

Any help appreciated
thanks
